Dr Thomas White

I'm an evolutionary ecologist and entomologist, and I lead the Sensory and Evolutionary Ecology (SEE) Lab. We spend our time using lab and field experiments, modelling, and meta-analysis to answer questions of adaptive evolution and behaviour. In particular we are interested in how organisms gather and exchange information to solve life's daily challenges, and the ecological and evolutionary consequences of these processes. Non-model insects and invertebrates have proven a particular source of inspiration, with butterflies, flies, and spiders being mainstays in the lab, though we gladly use any system appropriate for the questions at hand.

Our current research is broadly centred on three themes:

  1. Communication. All organisms need to gather and exchange information with the world at large, and we are broadly interested in understanding the mechanisms, causes and evolutionary consequences of this basic challenge. Current projects are focused on understanding how suites of traits coevolve to enable communication in ‘noisy’ natural environments, how the information encoded in diverse visual cues (colour, pattern, motion) is integrated to inform crucial decisions, and the vital role of communication in shaping local adaptation and survival amidst unpredictable environmental change. We also enjoy testing and extending methods for analysing colour and vision in nature, as well as developing software that improves the accessibility of such tools.
  2. Dis- and misinformation in nature. Deception and misinformation is rife in the natural world, including (and increasingly) among humans. Spiders pose as flowers to lure insects to their death, defenceless prey mimic the signals of the chemically defended to survive, and malicious or ill-informed actors stoke division via social media at unprecedented scale. We have an ongoing interest in misinformation, how it flows through biological and social networks, and its evolutionary consequences. The colour polymorphic lures of tropical spiders have proven a rich model in predator-prey deception, while flies present a window to sexual conflict, though many questions remain.
  3. Pollinators in natural and managed systems.How do flower-visiting insects find, select, and remember floral resources? Can pollinators weigh information across modalities to overcome noise? What is the value of lesser-studied systems, like syrphid and muscid flies, to crop pollination? We are keen to understand the role of non-traditional insects as pollinators, from both fundamental and applied perspectives. Current projects span floral foraging and sensory ecology in flies and butterflies, and how cues across modalities reinforce and/or interfere to affect decision-making.
